Computer - Guided Inferior Alveolar Nerve Lateralization With Simultaneous Prosthetic Driven Implant Placement Will be Performed on 10 Surgical Sides (Mandibular Quadrants) to Evaluate the Postoperative Neurosensory Disturbances Following Guided Inferior Alveolar Nerve Lateralization

Computer - Guided Inferior Alveolar Nerve Lateralization With Simultaneous Prosthetic Driven Implant Placement

The aim of this clinical trial is to primarily evaluate the postoperative neurosensory disturbances following guided inferior alveolar nerve lateralization with simultaneous implant placement in 10 surgical sides (mandibular quadrants distal to the mental foramen) either in males or females with age range from 30 to 75 years. The main questions it aims to answer are:

1. Will the postoperative neurosensory disturbances after the surgical intervention fade out and if not, will it be annoying to the patient?
2. Can we consider inferior alveolar nerve lateralization efficient substitute to short implants?
3. will the inserted implants going to be properly ossteointegrated at the site of osteotomy for lateralization?

Inclusion Criteria:

• Atrophic mandibular ridges distal to the mental foramen with residual alveolar bone height ≤ 8 mm above the IAN.
• The width of the alveolar ridge ≥ 6 mm, 3mm down from the alveolar crest.

Exclusion Criteria:

• All patients suffering from any systemic disease that may contraindicate implant surgery or affect bone healing and osseointegration of implant.
• Previous history of bone augmentation or implant placement in the site planned for nerve lateralization.
